The pace of #innovation in electric vehicles is mind-blowing. It's not just about #batteries, but also #electricdrives, #powerelectronics, #software, and #batterymanagement. Image
These advancements mean better #energyefficiency, increased range, and lower costs. With fewer parts, economies of scale will soon make electric vehicles as affordable as internal combustion engines. The future is electric! ⚡️🚗 #EVs #CleanTransportation Image
Long-haul trucking and farm & mining equipment pose interesting challenges. Will it be all #batteries or a combo of #fuelcells and batteries? My bet is on batteries dominating the field due to their innovation and scalability. Fuel cells are still in their early stages Image

Today and tomorrow, @G7 #Energy ministers meet in #Japan – a country, often considered a “laggard” on #energytransition. What is 🇯🇵’s energy system like and why is it so reluctant to step up #decarbonisation of its economy? A 🧵 1/19…
The “usual” arguments by the 🇯🇵 government when confronted with lack of both action and ambition on #energytransition:
1. #Japan is resource-poor
2. Japan’s geography limits #renewables build-out
3. Technologies & Innovation will solve the transition

How true are they? 2/19
Japan is indeed poor in some resources, most notably #fossilfuels. Fossil fuel based, its energy system is 88% dependent on #oil, #LNG and #coal imports. It has one of the least self-sufficient energy systems, dependent on #oil & gas from #MiddleEast & #coal from #Australia. 3/19 ImageImage

1/6 It's important for businesses to be aware of the rising energy costs. According to the World Bank, the cost of energy is expected to be 46% higher on average in 2023. This can significantly impact your business finances
#EnergyEfficiency #dellemc #powerbill
2/6 One solution to reduce energy costs is to adapt energy-efficient #servers. A study by the Environmental Protection Agency (EPA) found that a typical server in a data center uses an avg of 200 watts of power, resulting in an energy cost of $731/yr /server
3/6 By implementing more energy-efficient #servers, businesses can reduce energy costs by up to 80%. For example, replacing an older server with a newer, energy-efficient model can lead to substantial energy savings

Despite the energy crisis & unusual weather, growth in global electricity use slowed only slightly in 2022 from its pre-Covid trend

This shows the resilience & increasing importance of electricity today

And growth is set to accelerate in the years ahead: Image
Renewables & also nuclear power are set to cover almost all the growth in global electricity demand through 2025

This suggests a tipping point is near for power sector emissions

Governments need to act now to speed up the growth of low-emissions sources: Image
Emerging & developing economies in Asia are driving the faster growth in global electricity consumption

Over 70% of the rise in global electricity demand through 2025 comes from China, India & Southeast Asia

By 2025, a third of the world’s electricity will be consumed in China Image

There is massive potential for more #EnergyEfficiency in Texas. EE reduces customers' bills, increases reliability & creates jobs. There are 158,882 EE workers in Texas, according to an @E4theFuture report. Many more could be created by #txlege. 1/
There's massive potential for more EE jobs. #Texas is among the worst states for #EnergyEfficiency goals, and we're 36th per capita in EE jobs.

Even so, EE is the 3rd largest energy sector in Texas w/ 31,000 EE businesses employing nearly 159,000 Texans. #txlege #txenergy 2/
Over 6 million TX homes are >20 years old & pre-date statewide building codes. We could create jobs and make the grid more reliable and resilient by improving the energy efficiency of these homes which could lower energy use (and bills) by >40%. #energytwitter 3/

I had the dubious pleasure of developing a lit review on thermal comfort back in 2010 for DECC so perhaps less surprised than @Adam_Grant_Bell - a few less well set out thoughts in response
First - the reason for the lit review was some top civil servants & Ministers couldn’t seem to get their pointy heads around the fact some folks wouldn’t be able to pay back energy saving measures though bill savings (oh and could be cut off if they didn’t!).
The findings presented a big challenge with the Green Deal’s ‘golden rule’ as theoretical consumption was assumed to be much higher than real energy use (true in most homes but particularly the poorest households).

The @PUCTX is about to recommend a direction for a new market design called Performance Credit Mechanism (PCM) (aka Pretty much a Capacity Market). It won't fix the problems with the grid but it will cost consumers dearly. PUC has an open meeting on the PCM today. #txlege 1/
The biggest problems with it: it won't solve either of the biggest challenges facing the grid: long cold snaps and summer nights. The "credits" given to generators will be random and impossible to predict. You can't build a power plant on a credit generated at random hours.
Bank of America's energy analysts put out a note this week about the immanent adoption of the PCM: "We see the latest developments as a positive for incumbent IPPs." That's independent power producers like @nrgenergy, Vistra, Constellation & Exelon who will make a killing.

A few #TXenergy takeaways as we thaw:
1) The grid's still vulnerable. #ERCOT CEO requested an emergency order yesterday, writing ERCOT “may not be able to avoid the need to curtail firm load.” That is, outage risk was real. He cited “natural gas delivery limitations.” #txlege 1/
Heard about this from @shelbywebb, see below. The language from ERCOT CEO Vegas was clear: "the loss of power to homes and local businesses in the areas that may be affected by curtailments presents a far greater risk to public health and safety."…
2) Communications are still terrible. Not one state official held a press conference or did a media availability to inform the public of this letter or why it was needed. This from @adelauchida was a common experience among journalists yesterday.

Grid update: Demand forecast is much lower than last night but ERCOT missed its forecast by 23% last night so that's cold comfort. A miss that bad tonight & conditions would be tight. Reports of gas supply ⬇️ 8bcf overall, ~3bcf in the Permian. Gas/coal outages ~9.5GW. #txlege 1/
Add it all up & still low chance of outages tonight, though higher than last night, esp. given the massive demand miss. #ERCOT and @PUCTX simply have to get better at forecasting demand and improving #energyefficiency. More on that here: 2/…
I said coming into this the two biggest wild card were power demand & gas supply. The drops in gas output weren't enough to cause problems yet. I don't think this level of reduction would cause outages. Keepin an eye on it though. #energytwitter #natgas 3/

Why I don't think there will be power outages this week, a thread:
1) It'll be ~10° warmer than Uri w/no snow/ice so:
- peak demand will be lower
- shouldn’t be nearly as many issues for gas supply & power plants
2) Peak demand @ 10am instead of overnight
#txlege #txwx 1/
Peak demand forecast is 69.5GW. Peak during Uri was between 76-82GW. However, the power went out in the early morning hours of Feb 15 at ~69.5GW, so that is very high demand. *But* the peak hitting at 10am instead of 1am is a massive difference. #txenergy 2/
There is little to no expected snow or ice so at 10am:
1) we'll have lots of solar production (more on that below) and
2) workers can get to sites where there are freezing issues. In many cases, they couldn't during the Uri #texasblackouts 3/

"Residential demand is the low hanging fruit in Texas... For every dollar spent, the benefit reaped was roughly $3.80 in 2021...demand-side fixes would take less time & money compared with building new gas fired power plants." #txlege #txenergy 1/4…
"Texas households tend to use electric resistance heating, which involves an electricity-intensive system of warming up coils & then blowing air over them (much like hair dryers). Heat pumps, which use refrigerants, require much less electricity." 2/4
"@ACEEEdc estimates that implementing a set of residential energy efficiency & demand response measures in Texas would offset about 11.4 GW of winter peak load." But we haven't increased #energyefficiency at all since Uri!

The Senate weighed in on the grid & the @PUCTX's proposed market design changes last week. Today, the House State Affairs Cmte meets to ask questions of the PUC, #ERCOT, the Independent Market Monitor & industry. I'll tweet some highlights here. #txlege 1/…
@PUCTX Livestream is here and the first panel has just started.…

Another good summary of the events of last week from @rtoinsider and @tkleckner1 here…
Chair Lake starts by saying it was "misinformation" that extremes weren't included in the study. They in fact did not include Uri.

Here's the quote from the study: "The 1980-2019 sample does not include the extreme cold weather event caused by Winter Storm Uri in 2021... (cont.)

The Texas Senate dealt a major setback to the efforts of the PUC Chair & some generators attempting to redesign the #ERCOT market, telling them to hold off. The PUCT's biggest mistake? They never defined the problems they're trying to solve. 1/🧵
Unfortunately, it seems that #txlege is repeating that mistake. I think there are three major problems we need to solve: (1) prolonged extreme winter storms (2) hot summer evenings & (3) cost.

*There is no one thing that will solve all of these problems*…
We need to identify & diagnose the problem correctly. Acc'g to @FERC & @NERC_Official, during Uri, Texas had massive demand (spiked by inefficient heat) & frozen gas supply & power plants (made catastrophic by lack of effective regulation). #txenergy 3/

2022 was a big year for #EnergyEfficiency

A 🧵 on some of the ways that governments, businesses and citizens are looking to efficiency to address the energy and climate crises

Read more in @IEA’s just-released, Energy Efficiency 2022 report ➡️
The global economy is using energy 2% more efficiently than it did in 2021

That’s 4x better than the past 2 years - but only half the rate needed this decade to get on track for #NetZero

But there are signs that 2022 may be a turning point for #EnergyEfficiency progress
Global investments in efficiency grew significantly to $560 billion in 2022 - a 16% increase from last year

This was driven mainly by investment in EVs, up 47% from 2021

However, spending crucial to improving the efficiency of buildings has stalled. Much more is needed

#ERCOT Winter Seasonal Assessment is out. While ERCOT and @PUCTX disputed @FERC's October assessment that we would have a deficit of 18GW in extreme cold, ERCOT finds in an extreme event, we would be short 9-12GW which would result in lenghty outages. #txlege 1/
The biggest problem with the SARA report is they only account for three major problems:

- high demand
- high thermal outages
- low wind

They still don't account for gas supply disruption, which could make outages >9-12GW in the winter. This is not yet fixed. #txenergy 2/
Good to see ERCOT finally acknolwedge that extreme winter demand could reach 80GW. I still think that undershoots it a bit (@AndrewDessler & team think demand in Feb 2021 was 82GW) but is closer to reality than ERCOT has ever acknowledged before. 3/…

Big day at #txlege today. Hearing in Senate B&C focused on fixing the grid, proposed ERCOT market changes and in Sen Natural Resources on economic development programs (incl. for energy) and implementation of a bill that bans state investment in sustainable investors #txlege 1/🧵
Here's the first part of the agenda in Senate B&C. Mostly usual suspects. None of the panels will have represention for residential consumers, community groups, renewable energy, battery storage, academia, etc. #txlege #txenergy
